IMPROVEMENT lN MACHINES FOR STARCHING AND GLAZING CORDS, BRAIDS, &c.

Specification forming part of Letters Patent No.

December To all 'whom 'it may concern: A

Be it known that I, DONALD MCINROY, of the city, county, and State of New York, have invented a new and Improved Means for Sizingand Drying Cords, Braids, or other Fabrics; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying' drawings, and to the letters of reference marked thereon, wherein- Figure 1 is a plan, and Fig. 2 is an elevation, of my said apparatus.

The nature ot' my invention consists in 'a means for sizing and drying cords, braids, or other fabrics after 4being passed through a trough of starch or other suitable substance, and then subjecting the fabric to a regulated pressure between heated surfaces for producing a handsome gloss or nish to such material or fabric.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The process starts by drawing from a reel a length of cord, braid, covered skirt-wire, or any other textilefabric requiring to be starched and glazed. From the reel it is conducted th rough a trough of starch or other suitable glazing materal, and thence is made to pass over and in contact with the drying and glazing surfaces of my machine. The cord is first conducted along in contact with aconvoluted hollow pipe, b, heated by steam or otherwise. Said fabric is passed around then under the convolutions alternately, so as to produce an intimate contact of the fabric with the pipe, and also to give tension. The tension may be regulated by the length of the convolutions, or by passing the substance over a greater or less number of these bends, as the case may require. The friction of the fabric on the pipe d may be lessened by bending the convolutions alternately up and down, as seen in Fig. 3, so that the fabric will pass in nearlya straight line, but remain in contact on opposite sides with the pipe. From these pipes the material passes around and beneath the hollow cylinder c, thence over the heater d, beneath the reciprocating or ironing surface or plate e, a suitable motion to which is imparted by the cams or eccentricsf. The cord or fabric is thence conducted under and 51,471, dated December 12, 1865; antedated 7, 1865.

around the cylinder g, thence under the bottom ofthe heater d, thence over the cylinder c. The fabric may be passed back and fort-h through the machine in this manner as often as desired, and is guided by the cross-bars and vertical pins at t. From the cylinder c the material is drawn upon the reel or spool Now, as the cloth or yarn accumulates upon the reel @l it tends to make too great tension and strain, which is regulated as follows:

On the shaft 1 is a fixed pulle Y, 2, communica-ting by belt (see Fig. l) with pulley 3 on the shaftt ofthe reel. rlhe pulley 2 is driven by a friction-strap, 5, controlled by a screw passing through a lug on the pulley 6, so that by the friction of this strap, as regulated by its screw, the reel t' may be turned with more or less power to take up the fabric as delivered from the cylinder c. This pulley 6 is to be revolved by a band from the cylinder c or other source of motion.

The cylinders c and g have steam-pipes 7c introduced through their bearings or shafts, which shafts are formed hollow, and the steampipe united by a suitable packing to allow the shaft to turn 5 and in the pi pes 7c, at 7, are springvalves opening inward, so as to allow air to pass into the cylinder and prevent their collapsing in case of any sudden condensation of the steam in them. The water ofcondensation in the cylinders c and g is drawn off by the pipes l, which pass down inside the respective cylinders, as seen in Fig. 4, and form siphons to draw over the water and keep the cylinders nearly empty; and to prevent the siphons becoming empty and ceasing to operate the pipe Z may be carried up to a higher point than the bottom of the cylinders, as shown, so that the siphons will cease to act before the water comes below either end; hence they will alway`s be kept full and operate as soon as the level of the condensation-waterin the cylinderis higher than the outlet of l.

The heater d is formed hollow, and I prefer to employ jets of gas within to heat the same, as giving a higher heat than steam at atmospheric pressure, and by the recprocations of the ironer e, as kept down by its Weight or spring 8, the material is thoroughly dried and a polish imparted to the surface.

The cylinders g and c may be rotated by power applied through belts to the 'pulleys m 2. The hollow drierd and ironer e? applied as n, to cause the material to be drawn along and and for the purposes set forth.
